    摘要： A method and apparatus for improving the water balance in a power unit by providing the exhaust gas from the cathode side of the fuel cell as a feed gas to the combustion system condensing at least a portion of water present in the effluent from the combustion system in a condenser, and then transferring water vapor from the uncondensed portion of the effluent from the condenser to the gas fed to the cathode side of the fuel cell. Water from the exhaust gas from the cathode side of the fuel cell is either captured in the condenser, or is reused in the feed gas of the cathode side of the fuel cell. By humidifying the air fed into system with the water vapor present in the exhaust gas, water is not lost from the system. Instead, the air is being fed into the system is humidified with this water, which in turn allows the humidifier to operated at higher temperatures and/or use smaller radiators and fans and/or draw less parasitic power, thereby increasing overall system efficiency.

    摘要： An open steam generator system is disclosed which comprises a substantially enclosed vessel having an opening for exhausting steam generated and an opening for draining residual water from the vessel. Within the vessel also is a heat exchange coil having a heat transfer fluid circulating through its runs. The vessel also includes an injector for spraying water onto the heating coil to form steam. The disclosed steam generator achieves tolerance for low water quality by minimizing surface areas in contact with water. In addition, the system promotes self-cleaning of heat exchange surfaces using thermal shock to dislodge scale deposits.

    摘要： Metal strip 9 cast directly from the melt onto a cylindrical casting drum 20 is made more uniform in thickness and in structure by making the temperature of the casting surface and, therefore, heat transfer more uniform, thus reducing distortion of the casting surface. This is accomplished by a novel arrangement of helical coolant channels 25 extending below the casting surface 10 and in heat transfer relationship with the casting surface and being at an angle of between about 15.degree. and 75.degree. (and preferably between about 45.degree. and 75.degree.) to the drum axis. At least one coolant inlet 21 and one coolant outlet 22 supply and withdraw coolant to each channel. In one embodiment, inlets (21a, 21b) are alternated on the same side of the shell with outlets (22a and 22b) of adjacent channels so that the cooler regions around inlets and alternated with higher temperature outlet regions to balance the temperature around the surface.
